Egg Noodle Lasagna

Directions

1. Cook noodles according to package directions; drain. Add butter; toss to coat.
2. In a large skillet, cook beef over medium heat until no longer pink; drain. Spread a fourth of the spaghetti sauce into an ungreased 5-qt. slow cooker. Layer with a third of the noodles, a third of the beef, a third of the remaining sauce and a third of the cheeses. Repeat layers twice.
3. Cover and cook on low until cheese is melted and lasagna is heated through, about 3 hours.
